Patents by Inventor William C. Levengood

William C. Levengood has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Publication number: 20040158166
    Abstract: A method and apparatus is provided for detecting and recording a specific type of electric pulse induced in metal electrodes held by the palms of the hands of living tissue of humans, and by certain organic and inorganic models of such living tissue. The purely passive system detects the electric energy produced by the living source as it interacts with the crystalline lattice of conductive metal electrodes to produce a train of oscillating pulses, the amplitude of whose envelope decays as a linear function of log-time. Specific aspects of these pulses can be used to study the state of the living, or non-living, source and to detect changes in this state over time.

  • Patent number: 6023880
    Abstract: A method and apparatus for treating seeds with self-organized avalanches of electrons between electrodes (11, 12) as a cathode and an anode with seeds (13) between the anode and cathode or on the anode. Apparatus circuit (200) in a box (20) provides simultaneous DC and AC between the electrodes which creates the avalanche of electrons which project into the seeds. The seeds must be stored before planting. The seeds so treated have enhanced growth characteristics.

  • Patent number: 5288626
    Abstract: A method for increasing the proportion of mutants in a generation in a first plant species having a recognized and established phenotype involves the simultaneous somatic exposure of germinal plants of the species to contact with whole cells and associated material of a second species of plants, and to electrophoretic conditions. The plants of the first species are preferably in a germinal state, such as seeds or seedlings, while the whole cells and associated materials of the second species can be a seedling root tip, a seedling, a tissue macerate (suspended in either water or agar) root nodules, fruit tissue or root tissue. When the cells of the first and second species have different membrane potentials, the step of electrophoretic exposure can be carried out by simply placing the cells in contact with one another.
